N-Channel UniFET TM MOSFET
250 V, 44 A, 69 m Ω
Features
? R DS(on) = 69 m Ω (Max.) @ V GS = 10 V, I D = 22 A
? Low Gate Charge (Typ. 47 nC)
? Low C rss (Typ. 60 pF)

Applications
Description
UniFET TM MOSFET is Fairchild Semiconductor ’s high voltage
MOSFET family based on planar stripe and DMOS technology.
This MOSFET is tailored to reduce on-state resistance, and to
provide better switching performance and higher avalanche en-
ergy strength. This device family is suitable for switching power
converter applications such as power factor correction (PFC),
flat panel display (FPD) TV power, ATX and electronic lamp bal-
lasts.
